The Heartrak-2 cardiac event recorder is the right solution to assist in the diagnosis of transient symptoms suggestive of cardiac arrhythmia. At the onset of symptoms (such as dizziness, shortness of breath to palpitations), the patient simply places the credit-card size Heartrak-2 to their chest to record, store, and then send their ECG(s) to Cardiostation or any standard receiving station.
